Library Stacks Access: Update

Library in-person services and schedules will be increasing throughout the summer as we hire and train more student employees. At the beginning of the summer, reservations will still be required to enter Mullen. The Stacks will open for browsing on Monday, May 17. While our circulation staff is still focusing on remote delivery of materials and contactless book pickup, to borrow books from the Stacks you may either use the self-check machine located in the lobby or leave books in bags provided at the circulation desk to be charged out and picked up at a later scheduled time. The current status of all library services can be found in our Libraries COVID-19 Information Guide.

Study Space Reservations, January 6: Update

Repair of the water main break on the north side of Mullen Library is taking longer than anticipated. At this time, we do not know if we will have any water in the building on Wednesday, January 6, 2021. If you have made a study space reservation for tomorrow or plan to do that, consider this information and re-schedule if you are uncomfortable being in the building without access to water.

Book pickup is not affected.

We are sorry for any inconvenience.
